Kotori / Serious language learning
Learn the language, not the game
Kotori combines SRS, guided practice, language-specific tools, contextual AI and school workflows for calm, serious progress.
Introduction
A language platform for learners building real skill
Kotori is built for guided practice, retention and progress that survives outside the app.
The platform joins SRS, vocabulary, grammar, reading, listening, speaking, writing and AI assistance with tools for teachers and language schools. It can guide self-study, support lessons and turn class artifacts into the next learning loop.
